I am using After Effects 6.5 pro and have had some rendering issues. I guess I have a couple of questions. First, should more detailed effects take a long time to render when doing a ram preview? (by a long time I mean close to a minute for a 15 or 20 sec clip) My computer has a pentium 4 2.60 ghz processor with 1 gig of ram, is this enough to do everything that AE has to offer or should I look to upgrade?
